v2.0.0 — modernized runtime, configurable labels, reminder comments

First major release in 5+ years. Clean-slate rewrite on a supported runtime with several frequently-requested features.

⚠️ Breaking: the action now runs on Node 20 and the main entry moved to dist/index.js. Pin @v2 or @v2.0.0 — @1.2.0 continues to work but will not receive further updates.

Highlights

• Node 20 runtime (up from the deprecated Node 12).
• Configurable labels via the new upcoming-labels input — closes #70.
• Optional reminder comments via comment-on-overdue / comment-on-upcoming, with {{daysUntil}}, {{dueDate}}, {{issueNumber}} templating and duplicate-comment suppression — closes #55.
• Idempotent label reconciliation — stale labels are removed when the due date changes or the issue becomes overdue, fixing #75.
• dry-run input for easy first-time setup.
• Outputs: issues-processed and issues-changed.

Under the hood

• Bundled with @vercel/ncc; node_modules/ is no longer committed.
• npm audit clean (undici pinned via overrides).
• Live-API tests replaced with 29 mocked unit tests; CI verifies dist/ stays in sync.
• Dropped unused @slack/client; replaced moment with native Date.
